The MOJAVE program has been monitoring a statistically complete sample of 135 radio-loud active galactic nuclei (AGN) of the northern hemisphere using the Very Long Baseline Array (VLBA). This sample, dominated by low-peaked blazars, is here characterized for the first time in the hard X-ray regime by the use of Swift/BAT. Here, we present the hard X-ray flux and luminosity distributions and discuss a partial correlation of (beamed) radio and X-ray fluxes as well as their luminosities. Previous Swift/BAT surveys revealed 49 hard X-ray emitting blazars all over the sky. MOJAVE-1, extended by the blazar list of the southern VLBI program TANAMI, exhibits a large portion of hard X-ray emitting blazars (127 out of 169), more than doubling the known population in this energy regime.
